Las Vegas, Nov. 4, 2014 – At the heart of the new DynoMax^® Performance Exhaust systems for 2007-08 Chevrolet Tahoe, Avalanche, Suburban and GMC Yukon models is the powerful, performance DynoMax Ultra Flo™ welded muffler. The new systems posted a 13 horsepower gain and increase of 33-ft. lbs. of torque over the stock system in recent dyno testing.

The new systems – available at performance exhaust retailers nationwide –  are cat-back, single-exhaust designs.

The new DynoMax kits – which fit 2007-08 Chevy Tahoe/GMC Yukon 8-cylinder 4.8L and 5.3L engines (p/n 39436) and 2007-08 Chevy Avalanche and Suburban/GMC Yukon 8-cylinder 5.3L engines (p/n 39442)  – include 3-inch mandrel-bent stainless steel piping and tip. Each system was designed to follow OE routing and includes stainless steel construction to help provide longer life and added durability.

Both of the new systems include the popular DynoMax Ultra Flo muffler. This muffler is a stainless steel, fully welded design that has straight-through internal piping to help provide unrestricted exhaust flow and reduced backpressure. Each Ultra Flo welded muffler includes Continuous Roving Fiberglass (CRF) technology that helps to absorb unwanted interior drone while providing a rich, throaty performance sound. The muffler design is dyno-proven to flow up to 2,000 SCFM and to support up to 2,000 horsepower.

Each DynoMax kit includes all necessary hangers, brackets and accessories necessary for installation. Detailed, full-color instructions are included for a fast, easy system install.

An exclusive 90-day Performance and Sound Guarantee lets consumers try the system for 90 days. Consumers can return the product within 90 days for a full refund of its purchase price.
